Given keyboards/sirius/uni660/rev2/rev2.h contains both iso and ansi layout macros, the keymap folders keyboards/sirius/uni660/rev2/iso/keymaps and keyboards/sirius/uni660/rev2/ansi/keymaps should be merged to keyboards/sirius/uni660/rev2/keymaps which means updates to readme and such.

@zvecr if I understand how Via reads keymaps correctly, and the fact that the ISO and ANSI PCBs are wired differently rather than just a layout change, we need a separate Via keymap directory for each, correct? That would prevent having a unified keymap directory for rev2.

In which case, keyboards/sirius/uni660/rev2/rev2.h should not contain both LAYOUT macros, and instead a iso.h and ansi.h created in their respective directories. You will also need a config.h for both ansi and iso so that they have different product IDs.

However looking at your LAYOUT macros, you can also go with my original suggestion, one via keymap and use the via layout options to switch between iso and ansi.
